Unit 2 Saving the earth. Topic 3 SectionA教案 仁爱版英语九年级上册.doc

Section A教学设计一、教材分析：本课是九年级第二单元第三话题的第一课时。主活动是1a和2。1a 通过记者采访Jane，询问有关Jane 在环保组织的活动，引出话题内容：如何做一个环保人士。通过介绍在生活中如何践行环保行为，自然地用到本话题的功能意念：提出建议。在提出建议的同时，又引出本话题的语法：并列句。1b是个难度比较高的听力任务。它不是单纯地考查听写，而是要求学生在听懂内容的基础上，对材料进行归纳之后再填空。1c是用第一人称来转述1a的内容，旨在向学生传播环保理念。2是针对并列句而设计的专项语法训练。3a和3b是在考查学生的垃圾分类意识之后，再通过听对话来进行验证。4再次让学生对垃圾进行分类，以此来培养学生对垃圾再利用的环保理念。通过学习本课，可以增强学生的环保意识。培养学生在写作时运用连接词写出比较连贯的句子的能力。 二、教学目标：1.知识目标 掌握本课的重点词汇和短语，初步学习并列句和提建议。2.技能目标能够给别人提出合理的建议。能够正确地运用连接词写出并列句。能够把所听到的听力材料先归纳再填空。3.情感目标鼓励学生在日常生活中自觉践行环保行为。三、教学重难点：1. 教学重点 Words and phrases: nod, agreement, disagreement, protection, organization, recycle, can, give up, so that, encourage sb to do sth.be harmful to sb./sth.Sentences: We should reduce the waste we produce. We should use both sides of paper and reuse plastic bags. Its a pleasure. Recycling can protect the environment, and it can save money, too. So we encourage students to collect waste paper and soft drink cans. Grammar: compound sentence2. 教学难点： 根据句子需要，正确地选用连接词。理解含有定语从句和情态动词被动语态的句子。四、学习策略在1b任务中，要先听懂对话内容，再归纳填空。在2中，要明白不同的连接词的不同用法。首先弄清上下句的关系，再确定用哪个连接词。在3a中，要充分利用自己的生活经验和已有的知识。五、教学过程：教学环节教师活动学生活动设计意图热身1、Show some logos about environmental protection.Ask the Ss to say what they stand for.2、Lead the Ss to talk about how pollution affects the environment.看图讨论意义讨论污染如何影响环境。拓展视野，激发兴趣复习各种污染的影响及减少方法讲授新课I.
